The map displays 3000 nearby stars from the Hipparcos catalogue. The European Space Agency's Hipparcos satellite operated for four years between November 1989 to March 1993 and was dedicated to the measurement of stellar parallax and the proper motions of stars.

HeyWhat'sThat Cosmic VisibilityHeyWhat'sThat is a website that generates a horizon view for any given location. The site includes the option to open a 'Sky' view that overlays the celestial sphere with the horizon, visible summits and an azimuth-altitude grid for that location at the current time.

HeyWhat'sThat also uses the Google Earth browser plug-in to portray the night sky.

Star ViewerThis is my own mash-up of Google Sky and videos of celestial animations from the European Space Agency and YouTube.

A number of celestial objects are presented in a right hand menu. If you click on one of the menu items the celestial object is shown on a map of the night sky. If you click on the tagged object a video animation is then displayed on top of the map.

SIMBAD Astronomical Database and Google SkyIn design and interaction this mash-up resembles Google's own web based Sky. However it is so much more than Google Sky. When you search for a celestial object in Google Sky you are shown the resulting map tiles in your browser. If you undertake the same search in the SIMBAD Astronomical Database and Google Sky you not only get to view the stunning imagery of Google Sky but you receive all the data available from the SIMBAD database as well.
